GOLDEN CITY, Mo. -- A probable cause statement says a man accused of killing a 12-year-old southwest Missouri girl led authorities to her body, but he claimed she died from a fall.

KYTV-TV reports the autopsy indicates the girl was strangled. Barton County prosecutor Steven Kaderly released the probable cause statement Sunday, a day before Bourne is to be arraigned.

Investigators say in the probable cause statement that Bourne claims Adrianna Horton ran away from him, fell down and died as a result of falling. It says Bourne led investigators to a wooded area southeast of Golden City, where the girl’s body was found.

The statement also says there is evidence the girl was sexually assaulted.
